SAFETY-LOCK FOR DETECTING THE VIOLATION 0F CONTAINERS.

To all ywhom t may concern.'

Be. it 'known that I, SALVADOR ANCIRA (lancia, a citizen of Mexico, anda resident of' Guadalajara, State of Jalisco, Mexico, have inventedcertain new and useful Improvements in Safety -Locks for Detecting the'Violation of' Containers, of which the following `1s a specification.

My invention is an improvement in safety locks, and has for its objectto provide a device of the character specified adapted .for securingcontainers of every character in such manner that any attempt to gainaccess to the contents of the container will be indicated by the lock.

In the drawings: 1f` igure l is a perspective view of the im oved lock.;Y

`ig. 2 a section on the line A-A of Fig. 1.

In 'the present embodiment of the invention the lock consists of twosections, one of which, in boxes, for instance, may be attached to4 thebody of the box and the other to the cover, the said sectionsinterlocking when pressed together to prevent entrance to the boxwithout disclosing that it has been opened. That is, the arrangement issuch that the lock must be destroyed or torn from the container to gainaccess to the interiorthereof.

The improved lock consists of a section which is adapted for connectionwith one of the elements to be locked together, and a section adapted tobe connected with the other element. The first named section, which isformed of sheet metal of proper weight, is doubled upon itself to forman upper flap A and a lower flap C, the said fiaps extending at a veryacute angle with respect to ch other, and the uppermost flap A has pursor lugs D extending downwardly L-.st the edges of the flap C and adaptedto pierce the container wall andV to be clenched on the inner side ofthe wall to secure the sections A-C to the container.

The flap A ha he free end thereof bent downwardly an" ".wardly to lieapproximately paral'cl with the flap as indicated at B, and at nejunction between the Hap A and the [lange B there is an opening E for apurpose to bev presently described. The section G which is also ofAsheet metal has Specification of Letters Pat'ent.

spurs or lugs H which extend downwardly and are adapted to penetrate thematerial of the container and to be clenched on the inner face thereofto secure the section to the container, and this section has a tongue Fwhich is 'adapted to enter the slot E. This tongue F is reduced, beingof less width than the section G and formed by cutting away the edges ofthe section G at the tongue,l and the tongue is provided at\ its freeend with a lip I extending down wardly and backwardly at an acute angle6:; to the tongue.

This lip I, when the sections are locked together, is adapted to engagethe flange B to prevent disengagement of the sections without destroyingthe lock or tearing the same from the container. rIhe lip I forms noimpediment to the entranceof the tongue through the slot E, butabsolutely prevents disengagement, since a movement of' the section Gaway from the sections lil-C will result in the lip passing below theflange 'lil -through the space between the flange and the flap C, and nomanipulation of the section can possibly arrange the parts so that theymay be detached.

While the device is mentioned in connection with boxes, it is obviousthat it might be used with cords or ribbons, the sections beingconnected with the ends of the cords or ribbons and the said cords orribbons being adapted to pass around a box or the like. The fastener maybe used with containrs of paper, pasteboard, tin, glass or the like, andmay be used for fastening paper bags or containers of any characterwhatever.

I claim:

l. A lock of the character specied consisting of sections adapted forconnection with the parts to be fastened together, one sectionconsisting of upper and lower flaps .connected at one end, the upperflap having means for connecting the section tothe container, and thefree edge of the upper flap having an inwardly and downwardly extendingflange provided with a-slot at the junction of the flange with the flap,the. other section having means for Securing it to the container, andhaving a tongue adaptn ed to enter the slot and provided with adownwardly inclined'lip for engaging the roe ange to preventdisengagement of the secper wall, and having a slot at the junctiontions. of l'hfi flange with the section, the other sec- 2.
